| Abstract:
Thirty-two hardy, woolly aphid resistant rootstocks were selected from a 908 rootstock seedling population obtained from three crosses: Malus robusta 5 (R.5) x M.27, R.5 x Budagovsky 57490 and open-pollinated Ottawa 3. A trial was conducted in Frelighsburg, Quebec, a sub-station of Agriculture and Agri-Food Canada, to evaluate the rootstock seedlings using ‘Spartan’ as a scion. Several of the evaluated rootstocks were found to be dwarfing and efficient under Quebec environmental conditions. | |
